The present invention; generally stated,

. relates to machinery used in wooden box 10 tion for the so-calleslitting or cutting ,from' construction endh as more es eciel relationto a slitting machine as use 111 cigar box manufacture.

The leading object of the present iIlYQIl-r tion may be said to residein the provision of a novel form of mschln'e simple, eflicient, andrelatlvel inexpensive construc an integral structure of multiple height,complete box irames.

A iurther object resides in the provision of general details oiconstruction and in t e sec. of the invention Wilibe. more inllyr un'erstood fromthe following description taken in connection I with theaccompanying drawings tormmg part hereof, 2 and 1n 1 is s view sideelevation of a -mrachine embodying the invention Fig, 2 is a topor planView the 'eof.

guldes 56 011 table '1 under the guides till ion the box parts passthrough the cutting parts of the saw 5 and are separated. The lugs arebars connecting the two chains, the lower chain being lower than thetable top, and the sprocket set below the table top with plates 63 setabove them to make a sliding surface for the box. These chains entirelyencircle the guides 56 and their supporting members and the box entersthe enclosure at a time when no lug interferes. 36Qis adjustable twowayszhorizontally to guide different width box frames or structures; andto permit as small an opening as possible between itself and the chainlug 4 as lug 4 passes guide 36. The guides 56 are adjustable at 54 fordifferent width boxes and one of the guides 56 has spring compensationat 57 for slight variation in the different'box parts.

After the box parts are split at the front edge of the saw, the boxparts are guided by the guides to the end of the table, said box partsbeing propelled by the next following box part. The guides areadjustable for various sizes of box parts by clamping guide bracket 37at proper position and the guides 43 keep the saws from again cuttingthe box parts as the parts pass the rear end of the saw. The guard 41prevents anything from coming in contact with the saw at its rear aswell as holding down the split box parts. stood 'in the connection, areset to abut against the saw to deflect the box parts as the same passthe rear end of the saw, thus preventing the saw teeth from againcutting the box parts. The guard 41 is suitably held down, it beingunderstood that it is hinged atits front end to guide 55. The guard 41is hinged to the fixed guard 60, which guard is attached to guide 55.

The saw 5'is mounted with the shaft 44 and motor 6 which drives both ona plate 47 which is mounted on plate 48 by a swivel that permitsvertical aligning of the saw.

Plate 48 is mounted on plate 49 in such a manner as to permit aligningof the saw 5 horizontally. v

a The eccentric pin 13 on the gear 12 driven by the gear 11 on the shaft45 has a link 46 fastened to it which keeps an arm 27 moving forward andbackward. This arm 27 is clamped at 28 to a rock shaft 29 to which isfastened another arm 30, having a link 31 which is connected to thesliding plunger 2 which conveys the integral parts from table 1 to aposition which enables the chains 3 to continue their motion past thesaw 5. The gears and sprockets are designed to keep plunger 2 and lugs 4in unison.

As the plunger 2 pushes the box parts forward they are guided at 36 todirect the box parts to the proper position for the chains 3 to continuetheir forward motion. As the chains 3 continue forward after the box Theguide The guides 43, it is to be under parts are separated the box partstravel between guides 50 which are adjustable at 37 for different sizesof boxes.

The saw arbor 44 and motor shaft 7 are connected with a flexiblecoupling 46 and are mounted on a plate ,47which has adjustmentvertically and horizontally to align the saw 5 for a straight cut. Thesaw 5 revolves in a vertical plane upon horizontal shaft-44. It will beunderstood that after severing of box parts, bottoms are applied in theusual manner and which: forms -no part of the present invention.

I am aware that the invention may be embodied in'other specific formswithout departing from the spirit oressential attributes thereof, and Itherefore 'de'sirethe present embodimentto be considered in all"respects as illustrative and not restrictive' reference being had to theappended claims:
